get priceApr 12, 2015 Lithium has a higher reduction potential. If you also look at the electronegativities of just Lithium and Cesium then you would notice that the shielding effect is more prevalent in Cesium, thereby reducing the electronegativity and affecting the reduction potential. So Lithium however, just compared to Cesium, has a higher electronegativity.
